ILS: Instant Localization Scheme for Underwater Mobile Networks

Executive Summary

Mobile underwater networks have recently been proposed as a way to explore and observe the ocean with a wide area coverage at reasonable cost when compared to traditional tethered approaches (e.g., seabed sensors). To achieve this goal, a swarm of mobile sensors, e.g., Autonomous Underwater Vehicles (AUVs) such as REMUS and IVER2 or floats such as UCSD Drogues, can be deployed to the venue of interest for short-term ad hoc real-time aquatic missions such as oil and chemical spill monitoring, submarine detection, and surveillance. Mobile nodes monitor local underwater activities and report collected sensor data using acoustic multi-hop routing to other mobile nodes for collaboration or to a distant data collection center.
